UNITED STATES PATENT OFFICE am I. LARSON AND W. ANDERSON, OI CHICAGO,ILLINOIS, ASSIGHOBS 'I'O WESTERN ELEGIRIC PIANO COMPANY, OF CHICAGO,ILLINOIS, A CORPORATION OF ILLINOIS TALKING MACHINE Application filedAugust 19, 1927. Serial No. 214,066;

Our invention relates more particularly to talking machines employingrecord-disks and more especially to talking machines of the record-diskmagazine type.

The object, generally stated, is to provide improvements in machines ofthe general character above stated to the end that they will be betteradapted for satisfactory and positive operation.

Certain of the specific objects are to provide improved means foreffecting the automatic playing of a plurality of records in succession;to provide improved means for effecting selective operation of thevarious records charged into the magazine; to'prov de for the operationof the machine pneumatically to the end that the operation thereof willbe more positive and likelihood of impairment of the machine minimized;to provide improvements in the record-changing means; the means forremoving the stylus or needle from the record after the playing of thelatter; the returning of the stylus or needle and the tone arm to normalposit on and the lowering of the stylus or needle for the next playingoperation; and other objects as will be manifest from the followingdescription.

Figure 18 is a plan view of a suction regulatingbellows forming a part of the machine and provided for the purpose ofcontrolling the amount of suction produced in the machine by theoperation of the pump of Figs. 11, 12 and 13. Figure 19 is a view invertical sectional elevation of the mechanism of 18. Figure 20 is a rearview, with certain parts broken away. of the pneumatic mechanism bywhich the reproducer head of the machine is raised to lift the needlefrom the record at the conclusion of the playing of the latter andlocked in raised'position following which this head and the tone-arm areswung toward the outer edge of the record, and pneumatic mechanism bywhich the reproducer head is released for movement toward the record toseat the needle in the record-groove. Fig. 21 is a view in sideelevation of the mechanism of Fig. 20 which is viewed from the right inthis figure. Figure 22 is a 1plan view, partly sectioned, of ableedvalve coated in one..of the pneumatic-pipes of the machine. Figure23 is a section taken at the line 23 on Fig. 22 and viewed in thedirection of the arrow. Figure 24 is a detailed view of the valvemechanism which controls the rotatable record carrier mechanism orrecord magazine, the valve mechanism shown bein viewed from theleft-hand side of Fig. 1. T ig. 25 is a view in longitudinal sectionalelevation, with certain parts omitted, of the mechanism shown in Fig.24. Figure 26 is a face view of one of the ported rotatable disk membersforming a part of the valve mechanism of Figs. 24 and 25, this diskbeing viewed from the line 26 on Fig. 25 and in the direction of thearrow. Figure 27 is a similar view 'of a ported stationary valvediskcooperating with the valve disk 26, this disk being viewed from the line27 on Fig. 25 and in the direction of the arrow. Figure 28 is a faceview of another, movable, ported valve-disk cooperating with thevalve-disk of Fig. 26, this disk being viewed at the line 28 on Fig. 25and in the direction of the arrow. Figure 29 is a plan view oftone-armcontrolled valve-mechanism constituting one of the controllingelements of the pneumatic mechanism of the machine. Figure 30 is a viewin side elevation of the mechanism of Fig. 29. Figure 31 is a view inend elevation of the mechanism of Fig. 29. Fi re 32 is a plan view of aprimary control ox constitutinga part of the pneumatic mechanism of themachine. Figure 33 is a plan view of the box of Fig. 32 with the coverportion removed and one end thereof shown in section a Figure 34 is aside view of the primary control box. Figure 35 is a section taken atthe line 35 on Fig. 32 and viewed in the direction of the arrow. Fi re36 is an enlarged section taken at the line 36 on Fig. 32 and viewed inthe direction of the arrow.

Figure 44 is a view in the natureof a diagram showing the various pipe lines, neumatics and valve devicesconstituting the pneumatic control mechanism'for the machine; Fig. 45 isa plan view of a part of the mechanism for actuating the nmdle holder;and Figure 46, a view in elevation of which is movable to osition forplaying any of the records as esired. This carrying mechanism comprisesa shaft 55 journalled at its ends in bearings 56 and 57 supported on arigid frame work 58 located in the casin and firmly secured to thebottom thereo The shaft has rigidly secured thereto a disk 59 providedat a face thereof with radiatin rotatable spindles 60 the outer ends ofwhic are equipped with friction disks 61 and beyond these disks withrecord-supporting disks 62, the spindles 60 being continued outwardlybeyond the disks 62 and the records X positioned thereon, and threadedto receive nuts 63 adapted to screw down against the outer faces of therecords, through the central openings in which the s indles project. Thespipdles 60 are rotatably eld to the disk 59 by arings 64 and 65 throughwhich they extend, the inner ends of the spindles being provided withcollars 66 disposed at opposite sides ofthe bearings 65. The arrangementof the parts above described is such that the annular series of recordsare in line with the opening 54 in artition 51 and the uppermosthorizontallylsposed record registers with this opening.

The mechanism for driving the uppermost horizontal record comprises afriction-disk 67 mounted on a shaft 68 journalled in bearings 69 (Fig.3) carried by the frame 58, the driving disk 67 being located, as shown,in such position that it extends in frictional engagement with theunderside of the friction isk 61 of the uppermost spindle 60 and normalto this disk and operates to drive the latter by frictional contact. Theshaft 68 is driven by a motor 70, shown as an electric motor, throughthe medium of an endless belt 71 extending over a pulley 72 on thearmature shaft of the motor and a pulley 73 rigid on a shaft 74journalled in the frame 58, this shaft havin fixed thereon a pulley 75connected, by a rub er belt 76, to a pulley 77 rigid on the shaft 68.Thus the shaft-.68 is driven at all times during the operation of themotor 70.

The tone-arm of the machine is represented at 79, it being shown asformed of two sections 80 and 81 (Fig. 6). The section 80 is.
